Answer:

The answer would be 2. See steps in explanation.

Explanation:

We can break down this expression using the order of operation, or " PEMDAS ".

P - Parentheses
E - Exponents
M - Multiplication (can switch spots with division based on order from left to right)
D - Division
A - Addition (can switch spots with subtraction based on order from left to right)
S - Subtraction

#(-2)0 - (-2)1#

#-2 * 0 - (-2)1# Let's multiply first, since it's the first operation in PEMDAS we can do first.

#0 - (-2)1# We got #0# from the first step. We see a subtraction sign, but there is also multiplication, and we need to do multiplication first.

#0 - (-2)# We multiplied again, and now we're left with one thing left to do, subtract. Notice we are subtraction a negative, so we must add.

#0 + 2# This part is simple

#2#

**Our final answer is #2#.
